I just bought an iBook G4 10.4.11(Tiger) and need to move my Address Book from my iMac 10.5.7 (Leopard). I moved it via the Firewire and then the Address Book did not open in the iBook. I think Tiger has different Address Book software. Anyway, I copied over the Tiger Address Book Application and now it won't open at all. How do I fix this all?
